摘要
This paper displays the obtained results of the collected sediment deposited during 65 days on road surfaces (Torrelavega-Spain). Two types of samples are distinguished: aspired directly and collected after sweeping. For each type of sample it was determined the particle size distribution and heavy metals concentration. The results suggest that the heavy metals concentration tends to increase exponentially form with the decrease in the size fraction. The associated loading of metallic elements exponentially increases with the size fraction.
